BACKGROUND

The embodiments described herein relate generally to the field ofconverting fluorescent light assemblies into light-emitting diode(“LED”) light assemblies. LED light assemblies are more efficient,versatile, and durable than fluorescent light assemblies.

Fluorescent light assemblies have been in use since the 1930's and aretypically installed to provide general lighting of large indoor spacessuch as warehouses, schools, retail stores, or the like. Often, knownfluorescent lighting assemblies include a channel (or housing) in theform of an inverted trough, otherwise known as a “troffer.” The trofferis usually attached to, or recessed in, the ceiling. Lamp holders orsockets are attached to the troffer. A ballast is attached within thetroffer and electrical wiring attaches the ballast to the sockets. Poweris supplied to the ballast by electrical wiring brought into the trofferthrough the top or end of the troffer. The ballast and electrical wiringare covered with a ballast cover. One or more linear fluorescent lampsare then placed in the sockets for operation of the lighting fixture.

Other variations of fluorescent lighting assemblies are commonly knownas “strip fixtures.” Such fixtures typically include a channel affixedto either a wall or ceiling and covered with a channel cover. Lampsockets are attached to the outer surface of the channel cover. Aballast is attached within the channel and electrical wiring attachesthe ballast to the sockets. Power is supplied to the ballast byelectrical wiring brought into the channel through the top or end of thechannel. One or more linear fluorescent lamps are then placed in thesockets for operation of the lighting fixture. These lamps may be placedin parallel or in an end-to-end configuration. In instances where thelamps are place end-to-end the total length of the strip fixture mayexceed eight feet in length, or twice the length of a single fluorescentlamp.

Currently, fluorescent lighting assemblies are installed in abundance,due to the low cost and utilitarian use of fluorescent lights comparedwith traditional incandescent lights. More recently, the innovation ofLED lighting has provided a more advantageous alternative to fluorescentlighting. LED lighting does not use mercury, turns on moreinstantaneously, has a longer service life, is more versatile, andprovides greater efficiency than fluorescent lighting. Thus, there areknown methods of converting existing fluorescent lighting assemblies totake advantage of LED technology. However, such known methods are timeconsuming and labor intensive. Specifically, retrofitting fluorescentlighting fixtures usually requires closing down areas of a buildingduring the retrofitting process. Accordingly, the speed and efficiencywith which the retrofit process is completed is an important factor inconsidering a retrofit kit.

To accommodate the standard troffer size and design, which includes anopening that is shorter length than the bracket spacing needed to mountstandard length light tubes, some known retrofit kits employ specializedbracket that have a different (i.e., shorter) length than that of astandard troffer. Such specialized brackets are often “hard wired” withthe T5 or T8 LED light tubes pre-mounted in the bracket. Thus, when theLED light tube fails, replacement of the entire bracket may benecessary, and which may require time consuming and complicated rewiringof the bracket to exchange the LED light tubes. Some known retrofit kitsemploy multiple brackets to accommodate a standard length T5 or T8 lighttube within the troffer. Such known kits, however, are installed usingmultiple operations that can require measurement, multiple installers,or the like.

To accommodate the standard strip fixtures size and design, some knownretrofit kits employ lengthy channel covers (also referred to as “pans,”“trays,” or “brackets”) or multiple covers with electrical components ineach. Such known kits, however, are heavy and cumbersome to install,requiring multiple steps to install. For example, some known kitsrequire preassembly of separate components, such as brackets, lampsockets, and wire harnesses before the pans are installed to the stripchannel mounting fixture. Moreover, to account for the large lengths ofmany known strip light channels (e.g., greater than 8 feet), some knownretrofit kits include lengthy components, which are difficult to ship,store, and install. In other approaches, multiple retrofit kits may beemployed but the use of multiple kits will often necessitate thatmultiple electrical connections be established during installation. As aresult, such known kits will require multiple installers or multipleelectrical connections per fixture, slowing the pace of conversion.

Further, most known strip fixture channels accommodate pans havingeither a width of five inches or a width of 4.25 inches. Known retrofitkits cannot be used interchangeably, and must be purchased in one sizeor the other.

Thus, a need exists for improved devices, methods, and kits forconverting fluorescent light assemblies.

DETAILED DESCRIPTION

Devices, methods, and kits for converting fluorescent light assembliesare disclosed herein. In some embodiments, an apparatus includes abracket assembly having a first end portion, a second end portion, and acentral portion located between the first end portion and the second endportion. The first end portion includes a first socket that isconfigured to be electrically coupled to a first end portion of a LEDlight assembly. The second end portion includes a second socket that isconfigured to be coupled to a second end portion of the LED lightassembly. The central portion joins the first end portion and the secondend portion in such a manner that the second end portion can moverelative to the first end portion, allowing the bracket assembly totransition between a first configuration and a second configuration. Thebracket assembly has a first length when the bracket assembly is in thefirst configuration, and a second length when the bracket assembly is inthe second configuration. The second length is less than the firstlength.

In some embodiments, an apparatus includes a first bracket member and asecond bracket member. The first bracket member has a first end portionand a second end portion. The first end portion includes a firstconnector portion and a first socket, the first socket configured to beelectrically coupled to a first end portion of a LED light assembly. Thesecond bracket member has a first end portion and a second end portion.The first end portion of the second bracket member has a secondconnector portion configured to engage the first connector portion tomovably couple the second bracket member to the first bracket member.The second end portion of the second bracket member includes a secondsocket configured to be coupled to a second end portion of the LED lightassembly. The second bracket member is configured to rotate relative tothe first bracket member from a first position to a second position. Afirst longitudinal axis of the first bracket member and a secondlongitudinal axis of the second bracket member define a first bracketangle when the second bracket assembly is in the first position. Thefirst longitudinal axis and the second longitudinal axis define a secondbracket angle when the second bracket assembly is in the secondposition, the second bracket angle less than the first bracket angle.

In some embodiments, an apparatus includes a bracket assembly having afirst end portion, a second end portion, and a central portion betweenthe first end portion and the second end portion. The first end portionincludes a first socket configured to be electrically coupled to a firstend portion of a LED light assembly. The second end portion includes asecond socket configured to be coupled to a second end portion of theLED light assembly. The central portion is configured to deform suchthat the second end portion can move relative to the first end portionto transition the bracket assembly between a first configuration and asecond configuration. The bracket assembly has a first length when thebracket assembly is in the first configuration and a second length whenthe bracket assembly is in the second configuration. The second lengthis less than the first length.

In some embodiments, a method of installing a LED lighting fixture,includes transitioning a bracket assembly from a first configuration toa second configuration. The bracket assembly includes a first endportion having a first socket and a second end portion having a secondsocket. The bracket assembly has a first length when the bracket is inthe first configuration, and a second length when the bracket is in thesecond configuration. The first length is such that a LED light assemblycan be coupled to the first socket and the second socket. The secondlength is less than the first length. Once the bracket assembly istransitioned to the second configuration, it is moved into an innervolume of a troffer. The bracket assembly is then transitioned from thesecond configuration back towards the first configuration such that thefirst end portion and the second end portion of the bracket each contactan inner surface of the troffer. The bracket assembly is then fastenedto the inner surface of the troffer.

In some embodiments, a method of converting a lighting fixture from afluorescent lighting fixture to a light-emitting diode lighting fixtureincludes disconnecting power to the lighting fixture and removing afluorescent light component from a troffer of the lighting fixture.Removing the fluorescent light component may include removing afluorescent light tube from within the troffer, removing a wire coverfrom within the troffer, removing a fluorescent light bracket, removingany fluorescent lamp sockets from within the troffer, and removing aballast from within the troffer. Removing a ballast will expose anincoming power line. With the removal of the fluorescent lightcomponents, an electrical connector is coupled to the incoming powerline. A bracket assembly is then positioned so that a first socketattached to a first end portion of the bracket assembly and a secondsocket attached to a second end portion of the bracket assembly areoriented downward. The bracket assembly is bent in a first directionabout a transition point in a central portion of the bracket assemblyuntil a bracket length between the first end portion and the second endportion is less than an opening length of an opening into the troffer.The electrical connector is connected to an electronic assembly of thebracket assembly. The bent bracket is then moved into the troffer. Oncethe first end portion and the second end portion are each in contactwith an inner surface of the troffer, a force is exerted on the centralportion of the bracket assembly. The force is sufficient to bend thebracket assembly in a second direction. Once this is accomplished,captive fasteners are moved into the inner surface of the troffer,securing the bracket assembly.

In some embodiments, a method of installing a LED lighting fixtureincludes moving a bracket assembly such that a first bracket membercovers a first end portion of a mounting fixture. An end portion of thefirst bracket member includes a first socket configured to beelectrically coupled to a first end portion of a LED light assembly. Asecond bracket member of the bracket assembly is movably coupled to thefirst bracket member and suspended from the first bracket member duringthe moving. An end portion of the second bracket member includes asecond socket configured to be coupled to a second end portion of theLED light assembly. The first bracket member is secured to the first endportion of the mounting fixture with fasteners captively coupled to thefirst bracket member. Once the first bracket member is secured, thesecond bracket member is rotated relative to the first bracket memberuntil the second bracket member is in the desired location about asecond end portion of the mounting fixture. The second bracket member isthen secured to the second bracket member with fasteners captivelycoupled to the second bracket member.

The term “about” when used in connection with a referenced numericindication means the referenced numeric indication plus or minus up to10 percent of that referenced numeric indication. For example, “about100” means from 90 to 110.

As used herein, the singular forms “a,” “an,” and “the” include pluralreferents unless the context clearly dictates otherwise. Thus, forexample, the term “a member” is intended to mean a single member or acombination of members, “a material” is intended to mean one or morematerials, or a combination thereof.

The term “substantially” when used in connection with, for example, ageometric relationship, a numerical value, and/or a range is intended toconvey that the geometric relationship (or the structures describedthereby), the number, and/or the range so defined is nominally therecited geometric relationship, number, and/or range. For example, twostructures described herein as being “substantially parallel” isintended to convey that, although a parallel geometric relationship isdesirable, some non-parallelism can occur in a “substantially parallel”arrangement. By way of another example, a structure defining a widththat is “substantially five inches” is intended to convey that, whilethe recited width is desirable, some tolerances can occur when the widthis “substantially” the recited volume (e.g., 5 in). Such tolerances canresult from manufacturing tolerances, measurement tolerances, and/orother practical considerations (such as, for example, minuteimperfections, age of a structure so defined, a pressure or a forceexerted within a system, and/or the like). As described above, asuitable tolerance can be, for example, of ±10 percent of the statedgeometric construction, numerical value, and/or range. Furthermore,although a numerical value modified by the term “substantially” canallow for and/or otherwise encompass a tolerance of the stated numericalvalue, it is not intended to exclude the exact numerical value stated.

As used herein, the term “set” can refer to multiple features or asingular feature with multiple parts. For example, when referring to setof walls, the set of walls can be considered as one wall with multipleportions, or the set of walls can be considered as multiple, distinctwalls. Thus, a monolithically-constructed item can include a set ofwalls. Such a set of walls can include, for example, multiple portionsthat are either continuous or discontinuous from each other. A set ofwalls can also be fabricated from multiple items that are producedseparately and are later joined together (e.g., via a weld, an adhesive,or any suitable method).

In a common variant, a fluorescent lighting assembly (or luminaire)includes a troffer that is attached to or recessed in a ceiling. FIG. 1is a perspective view of a known troffer of a lighting fixture 100showing the inside of the troffer 101. Components such as lamp holders(not shown), also known as sockets or lamp sockets, are attached to thetop surface 103 of the troffer 101. The internal volume 102 of thetroffer 101 also includes components such as the light tubes (notshown), additional wiring (not shown), and/or a ballast 105. The ballast105 regulates the electrical current to the fluorescent light tubes andprovides sufficient voltage to start the fluorescent light tubes. Asshown, the standard troffer 101 includes a lip 104 that extends aroundthe opening into the internal volume 102. The lip 104 can be used, forexample, to assist in mounting the troffer 101 into the ceiling of thebuilding. The lip 104 of the troffer 101, however, forms an outer edgethat can impede the installation of new components when converting afluorescent lighting assembly to a LED lighting assembly. Specifically,the lip 104 can cause the length of the opening to be shorter than thelength of a fully assembled bracket to which standard length LED lighttubes are mounted.

Other variations of fluorescent lighting assemblies are commonly knownas “strip fixtures.” Such fixtures typically include a channel affixedto either a wall or ceiling and covered with a channel cover. Lampsockets are attached to the outer surface of the channel cover. Aballast is attached within the channel and electrical wiring attachesthe ballast to the sockets. Power is supplied to the ballast byelectrical wiring brought into the channel through the top or end of thechannel. One or more linear fluorescent lamps are then placed in thesockets for operation of the lighting fixture. These lamps may be placedin parallel or in an end-to-end configuration. In instances where thelamps are place end-to-end the total length of the strip fixture mayexceed eight feet in length, or twice the length of a single fluorescentlamp. While strip fixtures do not typically exhibit the same limitationsfor retrofit caused by the lip 104, this length presents retrofitchallenges.

The embodiments described herein provide a novel approach for convertingexisting fluorescent lighting assemblies without compromising the lengthof the LED light tubes that are installed into the troffers (e.g.,troffer 101) of the existing lighting fixtures, employing lengthyretrofit kits, or using multiple retrofit kits requiring multipleelectrical connections be established during installation. Simplystated, the embodiments described herein allow for the rapidinstallation of a bracket or bracket assembly for use with standardlength LED light assemblies (e.g., T5 or T8 tubes).

For example, FIGS. 2-5 show illustrations of a bracket assembly 190,according to an embodiment. The bracket assembly 190 includes a movablebracket 120 that contains the electrical wiring and sockets (the sockets164, 165) for converting an existing fluorescent lighting fixture into aLED lighting fixture. As described herein, the bracket assembly 190 cantransition between a first configuration (see FIGS. 2 and 5) and asecond configuration (see FIGS. 3-4) to facilitate installation withinan existing troffer 100. Specifically, when the bracket assembly 190 isin its second configuration, the bracket assembly 190 can be movedthrough the opening 106 clearing the lip 104 and into the interiorvolume 102 of the troffer 100. The bracket assembly 190 can then betransitioned to its first configuration to accommodate a standard-lengthLED light assembly 110.

As shown in FIG. 2, the bracket 120 has a first end portion 121, asecond end portion 122, and a central portion 123 between the first endportion 121 and the second end portion 122. While the particularembodiment illustrated in FIG. 2 shows the central portion 123 as beinglonger than, and perpendicular to, the first end portion 121 and thesecond end portion 122, this illustration is not intended to limit thepossible orientation in other embodiments of the central portion 123,the first end portion 121 and the second end portion 122. For example,in some embodiments, the central portion 123 may be shorter than thefirst end portion 121 or the second end portion 122 and placed along thesame longitudinal axis as the end portions.

The first end portion 121 defines a longitudinal axis A₁ (see FIG. 3),and includes (or is coupled to) a first socket 164 configured to beelectrically coupled to a first end portion 111 of a LED light assembly110. The socket 164 can be coupled to the first end portion 121 of thebracket 120 by any suitable mechanism. For example, in some embodiments,the socket 164 can be coupled to the first end portion 121 by amechanical fastener (e.g., a screw, a clip, or the like), by aninterference fit (e.g., within an opening defined by the bracket 120),by an adhesive, or by a weld joint. Because the socket 164 is coupled tothe first end portion 121 of the bracket 120, the socket 164 alsoprovides structural support to the LED light assembly 110 coupledthereto. The socket 164 (and any of the sockets described herein) can beany suitable socket, such as a pre-wired socket that can hold a standardT8 LED light tube. In some embodiments, the socket 164 (and any of thesockets described herein) can be a BJB model 26.292 series push throughlamp holder (e.g., model 26.292.1111.50) or a LEVITON 13661-SWP lampholder.

In various embodiments, additional sockets (not shown) may be coupled tothe first end portion 121 and configured to mechanically support the LEDlight assembly 110. For example, in some embodiments, the bracketassembly 190 can include 2, 3, 4, or more sockets, each configured tosupport an end portion of a LED light assembly. Moreover, in someembodiments, the bracket assembly 190 can optionally include anelectronics assembly 160. The electronics assembly 160 can be coupled toany portion of the bracket 120, and can include the wiring, connectors,and circuitry to electrically couple the socket 164 (and thus the LEDlight assembly 110) to a power source (not shown). For example, as shownin FIG. 2, in some embodiments, the electronics assembly 160 can includewiring 161 that is coupled to the socket 164, electronics component 163,and power connector 162. In other embodiments, however, the electronicsassembly need not include these components. In still other embodiments,the electronics assembly 160 can include a wireless controllerconfigured to receive a wireless communications signal and adjust powersupplied to the first socket via the power source in response to thewireless communication signal.

The second end portion 122 defines a longitudinal axis A₂ and includes asecond socket 165 configured to be coupled to and mechanically support asecond end portion 112 of the LED light assembly 110. In someembodiments, the second end portion 122 does not provide an electricalconnection between a power source (not shown) and the LED light assembly110 and/or does not include any electronic components nor other wiring.Thus, in some embodiments, the second socket 165 provides onlymechanical support to retain the LED light assembly 110 in the desiredposition (e.g., between the first socket 164 and the second socket 165,as shown in FIG. 2). The second socket 165 can be coupled to the secondend portion 122 of the bracket 120 by any suitable mechanism. Forexample, in some embodiments, the second socket 165 can be coupled tothe second end portion 122 by a mechanical fastener (e.g., a screw, aclip, or the like), by an interference fit (e.g., within an openingdefined by the bracket 120), by an adhesive, or by a weld joint. Thesecond socket 165 (and any of the sockets described herein) can besuitable socket, such as a pre-wired socket that can hold a standard T8LED light tube. In some embodiments, the second socket 165 (and any ofthe sockets described herein) can be a BJB model 26.292 series pushthrough lamp holder (e.g., model 26.292.1111.50) or a LEVITON 13661-SWPlamp holder. Moreover, although the bracket assembly 190 is shown asincluding two sockets 165 (only one is identified), in otherembodiments, the bracket assembly 190 can include any number of sockets.For example, in some embodiments, the bracket assembly 190 can include2, 3, 4, or more sockets 165, each configured to support an end portionof a LED light assembly.

The central portion 123 connecting the first end portion 121 to thesecond end portion 122 defines an axis of rotation A_(R), and includes afirst wall 191, a second wall 192, and a third wall 193. The first wall191 connects the first end portion 121 to the second end portion 122.The second wall 192 and the third wall 193 are each attached to thefirst wall 191, with the second wall 192 being opposite the third wall193. Collectively, the first wall 191, the second wall 192, and thethird wall 193 define a channel 194. In some embodiments, the channelcan contain the optionally included electronics component 163, wiring161 or any other components of the bracket assembly 190. In this manner,when the bracket assembly is installed, such components can be coveredand/or maintained in the enclosed channel. In some embodiments, thebracket 120 may also include an access panel (not shown, but see, e.g.,FIG. 9 showing the access panel 227) movably coupled about an accessopening (not shown, but see e.g., FIG. 9 showing the opening 237). Theaccess panel can provide access to the enclosed channel withoutrequiring that the bracket assembly 190 be removed from the innersurface of the troffer 100.

While FIG. 2 shows the second wall 192 and the third wall 193 in aconfiguration essentially perpendicular to the first wall 191, in otherembodiments, the walls may be at any selected angle and it is notnecessary that they be congruent. Although the second wall 192 and thethird wall 193 are shown as being attached to the first wall 191 alongouter edges of the first wall 191, in other embodiments, the second wall192 and the third wall 193 may be attached to the first wall 191 at anysuitable location across the first wall 191. In some embodiments, thesecond wall 192 and the third wall 193 may be shorter than the firstwall 191, and each of the three walls may be a different length. In yetother embodiments, the central portion 123 need not include the secondwall 192 and/or the third wall 193, and need not define a channel.

The central portion 123 is configured such that the second end portion122 can move relative to the first end portion 121. This movementenables the bracket assembly 190 to transition between a firstconfiguration, as shown in FIGS. 2 and 5, and a second configuration(See FIG. 3-5). When the bracket assembly 190 is in the firstconfiguration, the bracket assembly 190 has a first length L₁ as shownin FIG. 5. In this configuration, the distance between the first socket164 and the second socket 165 is defined by and/or is consistent withthe length of the LED light assembly 110. In this manner, when thebracket assembly 190 is in the first configuration, the LED lightassembly 110 can be coupled to (and between) the first socket 164 andthe second socket 165. In some embodiments, the LED light assembly 110includes a T8 LED light tube. Additionally, as shown in FIGS. 2 and 5,when the bracket assembly 190 is in the first configuration, thelongitudinal axis A₁ of the first end portion 121 and the longitudinalaxis A₂ of the second end portion 122 are substantially coaxial. Saidanother way, the longitudinal axis A₁ of the first end portion 121 andthe longitudinal axis A₂ of the second end portion 122 define a firstbracket angle that is about 180 degrees.

When the bracket assembly 190 is in the second configuration, thebracket assembly 190 has a second length L₂ as shown in FIG. 3, which isless than the first length L₁. Additionally, the second length L₂ isless than a length L_(t) of the opening 106 into the troffer 100. Inthis manner, when the bracket assembly 190 is in the secondconfiguration, the bracket assembly 190 can fit through the opening 106defined by the lip 104 of the troffer 100. Additionally, when thebracket assembly 190 is in the second configuration, the longitudinalaxis A₁ of the first end portion 121 and the longitudinal axis A₂ of thesecond end portion 122 form a second bracket angle θ. The second bracketangle can be any suitable angle. For example, in some embodiments, thesecond bracket angle θ is less than about 170 degrees. In otherembodiments, the second bracket angle θ is less than about 145 degrees.In other embodiments, the second bracket angle θ is less than about 120degrees. In yet other embodiments, the second bracket angle θ is betweenabout 80 degrees and about 100 degrees.

In use, the bracket assembly 190 can be transitioned between the firstconfiguration and the second configuration to facilitate installation ofthe bracket assembly 190 into an existing troffer 100 according to anyof the methods described herein. For example, prior to installation, thebracket assembly 190 can be transitioned from the first configuration(FIG. 2) to the second configuration (FIG. 3), with the second bracketangle θ being less than about 170 degrees. To transition the bracketassembly 190 from the first configuration to the second configuration, arotational force AA is applied to the bracket assembly 190 so that thefirst end portion 121 and the second end portion 122 of the bracketassembly 190 are brought closer together and the second length L₂ isestablished. Similarly stated, the second end portion 122 can be movedrelative to the first end portion 121 from a first position(corresponding to the first configuration of the bracket assembly 190)to a second position (corresponding to the second configuration of thebracket assembly 190). In instances involving mounting the bracketassembly in a troffer, as is shown in FIG. 3-5, the establishment of thesecond length L₂ will enable the bracket assembly 190 to be insertedpast the surrounding lip 104.

The first end portion 121 can be moved towards the second end portion122 in any suitable manner. For example, in some embodiments, thecentral portion 123 is configured to deform about the axis of rotationA_(R) when the bracket assembly 190 is transitioned between the firstconfiguration and the second configuration. In some such embodiments,the central portion 123 can define at least one perforation, opening,notch, or other feature to facilitate deforming the central portionabout the axis of rotation A_(R). In some such embodiments, the secondwall 192 and/or the third wall 193 can include an opening or a notch, ofthe types shown and described herein. In some such embodiments, thecentral portion 123 can include a stress point, such as may be createdby the reducing the thickness of the material along the axis of rotationA_(R). In still other embodiments, the first wall 191 may includeperforations positioned to facilitate deformation along the axis ofrotation A_(R) when the bracket assembly 190 is transitioned from thefirst configuration to the second configuration.

In other embodiments, however, the bracket assembly 190 can includemultiple pieces that are coupled together at a hinged or pinned joint tofacilitate movement of the first end portion 121 relative to the secondend portion 122. Similarly stated, although in some embodiments, thefirst end portion 121, the second end portion 122, and the centralportion 123 can be monolithically constructed, in other embodiments, anyof the first end portion 121, the second end portion 122, and thecentral portion 123 can formed from separately-constructed componentsthat are joined together. For example, in some embodiments, the firstend portion 121 and the second end portion 122 can be separatecomponents that are joined together via a rotational joint along theaxis of rotation A_(R).

After the bracket assembly 190 is in the second configuration, thebracket assembly can be moved, as shown by the arrow F, through theopening 106 and into contact with the mounting surface as shown in FIG.4. The continued exertion of the force F will return the bracketassembly 190 to the first configuration. In some embodiments, the forceF can be applied at or near the axis of rotation A_(R), thereby urgingthe bracket assembly 190 back towards the first configuration when thefirst end portion 121 and the second end portion 122 are in contact withthe upper surface of the troffer. Because the force F is applied at thecentral portion 123, it can be applied with a single hand. After thebracket assembly 190 has returned to the first configuration, thebracket assembly 190 can be fastened inside the troffer 100 using anysuitable mechanism. For example, in some embodiments, the bracketassembly can include a series of captive fasteners that can be fastenedto the troffer 100.

An example of a bracket 120 which may be monolithically constructed, orconstructed via other selected means, is illustrated in FIGS. 6-18.FIGS. 6-18 show illustrations of a bracket assembly 290, according to anembodiment. The bracket assembly 290 includes a movable bracket 220 thatcontains the electrical wiring and sockets (the sockets 264, 265) forconverting an existing fluorescent lighting fixture into a LED lightingfixture. As described herein, the bracket assembly 290 can transitionbetween a first configuration (see FIG. 15) and a second configuration(see FIG. 16) to facilitate installation within an existing troffer 100.Similar to that described above for bracket assembly 190, when thebracket assembly 290 is in its second configuration, the bracketassembly 290 can be moved through the opening 106 clearing the lip 104and into the interior volume 102 of the troffer 100. The bracketassembly 290 can then be transitioned to its first configuration toaccommodate a standard-length LED light assembly 210.

As shown in FIG. 15, the bracket 220 has a first end portion 221, asecond end portion 222, and a central portion 223 between the first endportion 221 and the second end portion 222. The first end portion 221and the second end portion 222 are each formed with a vertical (orlateral) edge 230 as is shown in FIGS. 9 and 10. The first end portion221 defines a longitudinal axis A₁ (see, e.g., FIGS. 15 and 16) that issubstantially normal to the vertical (or lateral) edge 230, and includes(or is coupled to) a set of first sockets 264. More particularly, asshown in FIGS. 8 and 9, the vertical edge 230 defines a series ofindentations 228 and corresponding mounting holes 231. Each socket 264is mounted within one of the indentations 228, and is retained in placeby a protrusion or clip that is locked within the mounting hole 231. Inother embodiments, however, the sockets 264 can be coupled to the firstend portion 221 of the bracket 220 by any suitable mechanism. Forexample, in some embodiments, the sockets 264 can be coupled to thefirst end portion 221 by a mechanical fastener (e.g., a screw, a clip,or the like), by an interference fit (e.g., within an opening defined bythe bracket 220), by an adhesive, or by a weld joint. Because thesockets 264 are coupled to the first end portion 221 of the bracket 220,the sockets 264 also provides structural support to the LED lightassembly 210 coupled thereto.

As shown in FIG. 8, the first sockets 264 are each configured to beelectrically coupled to a first end portion 211 of a LED light assembly210. The sockets 264 (and any of the sockets described herein) can besuitable socket, such as a pre-wired socket that can hold a standard T8LED light tube. In some embodiments, the sockets 264 (and any of thesockets described herein) can be a BJB model 26.292 series push throughlamp holder (e.g., model 26.292.1111.50) or a LEVITON 13661-SWP lampholder. Similar to that described above for bracket assembly 190,various embodiments may include any number of additional sockets (notshown) coupled to the first end portion 221, and the first end portion221 may be configured to accept the additional sockets within theindentations 228. As described in more detail below, the bracketassembly 290 can optionally include an electronics assembly 260 (seeFIG. 6). The electronics assembly 260 can be coupled to any portion ofthe bracket 220, and includes the wiring 261, connectors 262, andcircuitry (not shown) to electrically couple the sockets 264 (and thusthe LED light assembly 210) to a power source (not shown).

The second end portion 222 defines a longitudinal axis A₂ (see, e.g.,FIGS. 15 and 16) that is substantially normal to the vertical (orlateral) edge 230, and includes (or is coupled to a second set ofsockets 265. Similar to the first end portion 221, as shown in FIGS. 11and 12, the vertical edge 230 of the second end portion 222 defines aseries of indentations 228 and corresponding mounting holes 231. Eachsocket 265 is mounted within one of the indentations 228, and isretained in place by a protrusion or clip that is locked within themounting hole 231. In other embodiments, the second sockets 265 can becoupled to the second end portion 222 of the bracket 220 by any suitablemechanism. For example, in some embodiments, the second socket 265 canbe coupled to the second end portion 222 by a mechanical fastener (e.g.,a screw, a clip, or the like), by an interference fit (e.g., within anopening defined by the bracket 220), by an adhesive, or by a weld joint.Because the sockets 265 are coupled to the second end portion 222 of thebracket 220, the sockets 265 mechanically support a second end portion212 of the LED light assembly 210.

As shown, the second end portion 222 does not provide an electricalconnection between a power source (not shown) and the LED light assembly210 and/or does not include any electronic components nor other wiringof the electronics assembly 260. Thus, the second socket 265 providesonly mechanical support to retain the LED light assembly 210 in thedesired position (e.g., between the first socket 264 and the secondsocket 265). In other embodiments, however, the second sockets 265 canalso be electrically coupled and/or provide power to the LED lightassembly 210. The second sockets 265 (and any of the sockets describedherein) can be suitable socket, such as a pre-wired socket that can holda standard T8 LED light tube. In some embodiments, the second sockets265 (and any of the sockets described herein) can be a BJB model 26.292series push through lamp holder (e.g., model 26.292.1111.50) or aLEVITON 13661-SWP lamp holder. Similar to that described above forbracket assembly 190, the bracket assembly 290 can include any number ofsockets, each configured to support an end portion of a LED lightassembly, and the second end portion 222 may be configured to accept theadditional sockets within the indentations 228.

The central portion 223 connecting the first end portion 221 to thesecond end portion 222 defines bend axis n A_(B) (see, e.g., FIGS.13-16). Referring to FIGS. 14-16, the central portion 223 includes afirst wall 291, a second wall 292, and a third wall 293. The first wall291 connects the first end portion 221 to the second end portion 222.The second wall 292 and the third wall 293 are each attached to thefirst wall 291, with the second wall 292 being opposite the third wall293. Collectively, the first wall 291, the second wall 292, and thethird wall 293 define a channel 294. In some embodiments, the channel294 can contain the optionally included electronics assembly 260 or anyother components of the bracket assembly 290. In this manner, when thebracket assembly 290 is installed, such components can be covered and/ormaintained in the enclosed channel. As shown in FIGS. 7-9, the bracket220 also includes an access panel 227 movably coupled about an accessopening 237. The access panel can provide access to the enclosed channel294 without requiring that the bracket assembly 290 be removed from theinner surface of the troffer. For example, in some embodiments, theelectronics assembly 260 (including the wiring or connectors) can beaccessed for service or replacement after the bracket assembly has beeninstalled, and without requiring removal of a portion of the bracketassembly 290. In some embodiments, the access panel is secured by afastener 225 as shown in FIG. 9. Some embodiments will include willinclude a pre-attached safety label 270 affixed near the access panel227, though the label may be placed at any desired location along thebracket 220.

As shown, each of the second wall 292 and the third wall 293 defines anotch 224 that facilitates bending or deforming of the central portion223 and/or the bracket 220 along the bend axis A_(B). Thus, the notches224 are aligned with the bend axis A_(B). As illustrated in FIGS. 17 and18, the notch 224 has a “V” shape defined by opposing edges 295 of theselected wall section, and defines a notch angle α. The notch angle αcan have any suitable value to facilitate deformation at the bend axisA_(B). For example, in some embodiments, the notch angle α can be up toabout 45 degrees. In other embodiments, the notch angle α can be betweenabout 15 degrees and about 30 degrees. Moreover, although the notches224 are shown as having a specific shape, in other embodiments, thesecond wall 292 and/or the third wall 293 can include any opening or cuttherein. Such openings can be any shape including, but not limited to, acut in the wall section, a “U” shaped void, or a void where the opposingedges 295 each form about a 90-degree angle with the first wall 291. Insome embodiments, the configuration for deformation may not include anotch, but rather may rely on the inclusion of a stress point, such asmay be created by the reducing the thickness of the material from whichthe central portion is constructed at the bend axis A_(B). In stillother embodiments, the first wall 291 may include perforationspositioned to facilitate deformation at the bend axis A_(B) when thebracket assembly 290 is transitioned from the first configuration to thesecond configuration.

In some embodiments, the second wall 292 and the third wall 293 may beconfigured to be essentially perpendicular to the first wall 291, but inother embodiments, the walls may be at any selected angle and it is notnecessary that they be congruent. Although the second wall 292 and thethird wall 293 are shown as being attached to the first wall 291 alongouter edges of the first wall 291 (See FIG. 15), in other embodiments,the second wall 292 and the third wall 293 may be attached to the firstwall 291 at any suitable location across the first wall 291. In someembodiments, the second wall 292 and the third wall 293 may be shorterthan the first wall 291, and each of the three walls may be a differentlength. In yet other embodiments, the central portion 223 need notinclude the second wall 292 and/or the third wall 293, and need notdefine a channel.

The central portion 223 is configured such that the second end portion222 can move relative to the first end portion 221. This movementenables the bracket assembly 290 to transition between a firstconfiguration, as shown in FIG. 15, and a second configuration as shownin FIG. 16. When the bracket assembly 290 is in the first configuration,the bracket assembly 290 has a first length L₁ as shown in FIG. 15. Inthe first configuration, the distance between the first socket 264 andthe second socket 265 is defined by and/or is consistent with the lengthof the LED light assembly 210. In this manner, when the bracket assembly290 is in the first configuration, the LED light assembly 210 can becoupled to (and between) the first socket 264 and the second socket 265.In some embodiments, the LED light assembly 210 includes a T8 LED lighttube. Additionally, when the bracket assembly 290 is in the firstconfiguration, the longitudinal axis A₁ of the first end portion 221 andthe longitudinal axis A₂ of the second end portion 222 are substantiallycoaxial. Said another way, the longitudinal axis A₁ of the first endportion 221 and the longitudinal axis A₂ of the second end portion 222define a first bracket angle that is about 180 degrees.

When the bracket assembly 290 is in the second configuration, thebracket assembly 290 has a second length L₂ as shown in FIG. 16, whichis less than the first length L₁. Additionally, the second length L₂ isless than a length L_(t) of the opening 106 into the troffer 100 shownin FIG. 3. In this manner, when the bracket assembly 290 is in thesecond configuration, the bracket assembly 290 can fit through theopening 106 defined by the lip 104 of the troffer 100. Additionally,when the bracket assembly 290 is in the second configuration, thelongitudinal axis A₁ of the first end portion 221 and the longitudinalaxis A₂ of the second end portion 222 form a second bracket angle (notshown, but see, e.g., FIG. 3 showing the bracket angle θ). The secondbracket angle can be any suitable angle. For example, in someembodiments, the second bracket angle is less than about 170 degrees.

In use, prior to installation, the bracket assembly 290 can betransitioned from the first configuration (FIG. 15) to the secondconfiguration (FIG. 16), with the second bracket angle θ being less thanabout 170 degrees. To transition the bracket assembly 290 from the firstconfiguration to the second configuration, a rotational force isapplied, as indicated by the arrows BB in FIG. 16, to the bracketassembly 290 so that the first end portion 221 and the second endportion 222 of the bracket assembly 290 are brought closer together andthe second length L₂ is established. Similar to that described above forbracket assembly 190 and shown in FIGS. 3-5, for instances involvingmounting the bracket assembly in a troffer, the establishment of thesecond length L₂ will enable the bracket assembly 290 to be insertedpast the surrounding lip 104.

The first end portion 221 can be moved towards the second end portion222 in any suitable manner. For example, in this embodiment, the centralportion 223 is configured to deform about the bend axis A_(B) when thebracket assembly 290 is transitioned between the first configuration andthe second configuration, as illustrated in FIGS. 15-16. In otherembodiments, however, a bracket can deform about any other suitablelocation or axis. In yet other embodiments, a bracket can deform aboutmultiple different axes.

After the bracket assembly 290 is in the second configuration, thebracket assembly can be moved (in a similar manner as shown by the arrowF in FIGS. 3-4) through a troffer opening (e.g., the troffer opening106) and into contact with the mounting surface. The continued exertionof an upward force will return the bracket assembly 290 towards thefirst configuration. In some embodiments, the upward force can beapplied at or near the bend axis A_(B), thereby urging the bracketassembly 290 back towards the first configuration when the first endportion 221 and the second end portion 222 are in contact with an uppersurface of the troffer. Because the upward force is applied at thecentral portion 223, it can be applied with a single hand.

After the bracket assembly 290 has returned to the first configuration,the bracket assembly 290 can be fastened inside the troffer 100 usingany suitable mechanism. For example, as shown, the bracket 220 includeswith a series of mounting flanges 226 defining mounting holes 232. Insome embodiments, a series of fasteners (e.g., screws) can be captivelyfastened within the holes 232. Thus, a user can support the bracketassembly 290 by applying an upward force about the bend axis A_(B) witha first hand, while installing the captive fasteners to secure theflanges 226 to the mounting surface with a second hand.

As described briefly above, in some embodiments, the bracket assembly290 can include the electronics assembly 260. The electronics assembly260 includes the wiring 261 that is coupled to the sockets 264 and thepower connector 262. This arrangement allows the bracket assembly 290 tobe easily coupled to a power source (not shown), such an A/C powersource. In some embodiments, the electronics assembly 260 includes asecond connector (not shown) that is matingly coupled to the connector262. In use, the mating connector is removed from the connector 262 andcoupled to the power line within the troffer (not shown). Then, duringinstallation the mating connector (coupled to the power line) can berecoupled to the connector 262, thereby providing an efficient mannerfor electrically coupling the bracket assembly 290 to the power source.In other embodiments, however, the electronics assembly need not includethese components. In still other embodiments, the electronics assembly260 can include a wireless controller configured to receive a wirelesscommunications signal and adjust power supplied to the first socket viathe power source in response to the wireless communication signal. Instill other embodiments, the electronics assembly 260 can include atimer, dimmer, or any other electronic device to enhance thefunctionality of the lighting assembly.

Although the bracket 220 is shown and described as including a series ofmounting flanges 226, in other embodiments, a bracket can include anysuitable mounting portion and/or flange configuration. For example, insome embodiments, a bracket can include elongated flanges. Moreover, insome embodiments, a bracket can include any suitable access panel,wiring arrangement, or the like. For example, FIGS. 19-21 show a bracketassembly 490 according to an embodiment. The bracket assembly 490includes a bracket 420 including a first end portion 421, a second endportion, and a central portion 423. The bracket assembly 490 is similarin many respects to the bracket assembly 290 described above, andtherefore certain aspects (e.g., sockets, wiring, etc.) are notdescribed in detail below.

The central portion 423 of the bracket 420 includes a deformableportion, similar to that defined by the notches 224 and/or bend axisA_(B) described above, which allows the bracket 420 to bend between afirst configuration and a second configuration. In this manner, similarto that described above for bracket assembly 290, the central portion423 provides the flexibility to clear the outer lip of a troffer (e.g.,the outer lip 104) so that the bracket 420 may be mounted into anexisting light fixture, as described herein. As shown, the centralportion 423 includes a first wall 491, a second wall 492, and a thirdwall 493. The first wall 491 connects the first end portion 421 to thesecond end portion (not shown). The second wall 492 and the third wall493 are each attached to the first wall 491, with the second wall 492being opposite the third wall 493. Collectively, the first wall 491, thesecond wall 492, and the third wall 493 define a channel 494. In someembodiments, the channel 494 can contain any optionally includedelectronics components, such as the wiring 461, a retention clip 466, orany other components of the types shown and described herein. In thismanner, when the bracket assembly 490 is installed, such components canbe covered and/or maintained in the enclosed channel.

In some embodiments, the bracket 420 also includes an access panel 427movably coupled about an access opening 437. The access panel canprovide access to the enclosed channel. In some embodiments, the accesspanel is secured by a fastener 425 as shown in FIG. 20. The access panel427 can be of any suitable length, and can have any suitable mechanismfor “opening” or allowing access after the bracket 420 has beeninstalled. In this manner, the electronics assembly (including thewiring or connectors) can be accessed for service or replacement afterthe bracket 420 has been installed, and without requiring removal of aportion of the bracket 420. In some embodiments, the access panel 427extends from the first end portion 421 of the bracket to the centralportion 423 of the bracket 420. In some embodiments, the access panel427 is secured by a screw, retention clip, magnet or other means. Insome embodiments, the access panel 427 is secured by a quarter-turnfastener 425 (FIGS. 19-20), which allows for tool-less maintenance ofthe light assembly once the bracket assembly 490 is installed. Thequarter-turn fastener 425 has a clip that fits through a hole in thecover of the access panel 427 and the bracket 420, and is locked intoplace with a quarter turn.

The bracket 420 includes two flanges 426. As shown in FIG. 19, theflanges 426 are elongated and extend along the bracket 420 from thefirst end portion 421 to a break point within the central portion 423,and from break point to the second end portion (not shown). The breakpoint can be, for example, adjacent a notch, bend axis or the like (notshown). As shown in FIG. 20, the flanges 426 are formed with mountingholes 432. In some embodiments, captive fasteners (not shown, butsimilar to the captive fasteners 333 shown and described with referenceto FIG. 24) are pre-loaded and employed to secure the bracket 420 withinthe troffer.

FIG. 22 illustrates a method 10 of installing a LED lighting fixtureaccording to an embodiment. Although the method 10 is described inconjunction with the bracket assembly 290 shown and described above, inother embodiments, the method 10 can be performed using any suitablebracket assembly described herein. The method includes transitioning abracket assembly from a first configuration to a second configuration,at 12. The bracket assembly can be, for example, the bracket assembly290, and includes a first end portion (e.g., the first end portion 221)having a first socket (e.g., the first socket 264) and a second endportion (e.g., the second end portion 222) having a second socket (e.g.,the second socket 265). The bracket assembly has a first length when thebracket is in the first configuration, and a second length when thebracket is in the second configuration. The first length is such that aLED light assembly (e.g., the light assembly 210) can be coupled to thefirst socket and the second socket. The second length is less than thefirst length.

In some embodiments, the method 10 optionally includes electricallycoupling the first socket to a power source, at 14. The coupling can beperformed, for example, by coupling a connector (e.g., the connector262) to a mating connector on an A/C power line. In some embodiments,the mating connector can be included as part of the retrofit kit.

Once the bracket assembly is transitioned to a second configuration, thebracket assembly is moved into an inner volume of a troffer, at 16. Bymoving the bracket assembly into the troffer when the bracket assemblyis in its second configuration, the length of the bracket assembly canbe less than a length of an opening into the troffer. Thus, the bracketassembly can pass into the opening easily. In some embodiments, thebracket assembly is moved into the inner volume with a single hand.

The bracket assembly is then transitioned from the second configurationback towards the first configuration such that the first end portion andthe second end portion of the bracket each contact an inner surface ofthe troffer, at 18. In some embodiments, transitioning the bracketassembly from the first configuration to the second configurationincludes bending a central portion of the bracket assembly. For example,in some embodiments, the central portion defines at least one of aperforation, a notch (e.g., the notch 224), or an opening, and thecentral portion can be deformed by applying a force about theperforation, notch or opening.

Upon reestablishing the first configuration, the bracket assembly isfastened to the inner surface of the troffer, at 19. In someembodiments, the bracket assembly can include a series of flanges ormounting surfaces (e.g., the flanges 226) to which a series of fastenersare captively coupled, as described herein. In such embodiments, thecaptive fasteners can be coupled to the surface of the troffer. In someembodiments, a user can support the bracket assembly by applying anupward force with a first hand, while installing the captive fastenersto secure the flanges to the mounting surface with a second hand.

FIG. 23 illustrates a method 20 of installing a LED lighting fixture,according to an embodiment. The method includes removing the existinglighting components from within the troffer, at 22. This includesdisconnecting power to the lighting fixture and removing a fluorescentlight component from a troffer of the lighting fixture. Removing thefluorescent light component may include removing a fluorescent lighttube from within the troffer, removing a wire cover from within thetroffer, removing a fluorescent light bracket, removing any fluorescentlamp sockets from within the troffer, and removing a ballast from withinthe troffer. Removing a ballast will expose an incoming power line.After the removal of the fluorescent light components, an electricalconnector is coupled to the incoming power line.

A retrofit bracket assembly of the types shown and described herein(e.g., the bracket assembly 290) is then installed into the troffer, at24. This can include preparing the A/C power line to be coupled theelectronics assembly (e.g., the electronics assembly 260) of the bracketassembly. For example, a male end of a quick disconnect fitting can beremoved from the female end (e.g., the connector 262) coupled to theelectronics assembly. The male end can be coupled to the power line.

The bracket assembly is then positioned so that a first socket attachedto a first end portion of the bracket assembly and a second socketattached to a second end portion of the bracket assembly are orienteddownward, at 24B. The bracket assembly is bent in a first directionabout a transition point in a central portion of the bracket assemblyuntil a bracket length between the first end portion and the second endportion less than an opening length of an opening into the troffer (see24C). The electrical connector is then connected to the correspondingelectronic connector (e.g., connector 262) of the bracket assembly. Thebent bracket is then moved into the troffer. Once the first end portionand the second end portion are each in contact with an inner surface ofthe troffer, a force is exerted on the central portion of the bracketassembly. The force is sufficient to bend the bracket assembly in asecond direction. Once this is accomplished, captive fasteners are movedinto the inner surface of the troffer, securing the bracket assembly.

In some embodiments, the bracket 220 (and any of the brackets describedherein) can be monolithically constructed. In other embodiments,however, the bracket 120 (and any of the brackets described herein) maybe formed from separately-constructed components. For example, FIGS.24-37 show illustrations of a bracket assembly 390, according to anembodiment, which is not monolithically constructed. The bracketassembly 390 contains the electrical wiring 361 and sockets (the sockets364, 365) for converting an existing fluorescent lighting fixture into aLED lighting fixture. As described herein, the bracket assembly 390 cantransition between a first configuration (see FIG. 33) and a secondconfiguration (see FIG. 31) to facilitate installation of the bracketassembly 390. For example, in some embodiments the bracket assembly 390can be coupled about a strip mounting fixture, and can accommodate LEDlight tubes arranged in an end-to-end arrangement.

As shown in FIG. 24, the bracket assembly 390 has a first bracket member320 and a second bracket member 340. The first bracket member 320 is aseparately constructed member than the second bracket member 340. Asdescribed herein, the second bracket member 340 can be coupled to thefirst bracket member 320 during an installation operation. Moreover, thesecond bracket member 340 is configured to rotate relative to the firstbracket member 320 between a first position and a second position. Thisarrangement facilitates installation of the bracket assembly 340 by asingle user.

The first bracket member 320 defines a longitudinal axis A₁ (FIG. 25showing the axis A₁) and includes a first end portion 321 and a secondend portion 322. The first end portion 321 of the first bracket member320 includes a first connector portion 335 and a series of first sockets364 configured to be electrically coupled to a LED light assembly,similar to that described above for bracket assemblies 190 and 290. Asshown, the first connector portion 335 is a slot within which the tabs352 of the second connector portion 351 (of the second bracket member340) are received. In other embodiments, however, the first connectorportion 335 can be any suitable mechanism or structure to facilitatecoupling the first bracket member 320 to the second bracket member 340.

As shown in FIGS. 29 and 30, the first end portion 321 defines a seriesof openings 328 and corresponding mounting holes 331. Specifically, eachopening 328 is between a pair of mounting holes 331. Each of the sockets364 is mounted within one of the openings 328, and is retained in placeby a protrusion or clip that is locked within the mounting hole 331. Inparticular, two first sockets 364 are coupled within each opening 328,as shown in FIG. 30. As shown in FIG. 29, the pair of first sockets 364is oriented in an opposed fashion. Specifically, the opening of onesocket 364 is oriented towards the second end portion 322 (and thecorresponding second socket 365 at the second end portion 322) and theother socket 364 is oriented away from the second end portion 322 andtowards the second end portion 342 of the second bracket member 340. Inthis manner, one of the sockets 364 (and its corresponding second socket365) is configured to be electrically coupled to a first LED lightassembly (not shown) that is aligned with and supported by first bracketmember 320, and the other socket 364 (and its corresponding secondsocket 365) is configured to be electrically coupled to a second LEDlight assembly that is disposed end-to-end with the first LED lightassembly, and that is aligned with (and supported by the second bracketmember 340). Similarly stated, this arrangement allows for theelectrical connections for both LED light assemblies to originate withinthe first bracket member 320.

In other embodiments, however, the sockets 364 can be coupled to thefirst end portion 321 of the first bracket member 320 by any suitablemechanism. For example, in some embodiments, the sockets 364 can becoupled to the first end portion 321 by a mechanical fastener (e.g., ascrew, a clip, or the like), by an interference fit (e.g., within anopening defined by the bracket 220), by an adhesive, or by a weld joint.Because the sockets 364 are coupled to the first end portion 321 of thefirst bracket member 320, each socket 364 also provides structuralsupport to an LED light assembly.

The first sockets 364 are each configured to be electrically coupled toa first end portion of a LED light assembly (not shown). The sockets 364(and any of the sockets described herein) can be any suitable socket,such as a pre-wired socket that can hold a standard T8 LED light tube.In some embodiments, the sockets 364 (and any of the sockets describedherein) can be a BJB model 26.292 series push through lamp holder (e.g.,model 26.292.1111.50) or a LEVITON 13661-SWP lamp holder. As describedin more detail below, the bracket assembly 390 can optionally include anelectronics assembly 360 (see FIG. 25). The electronics assembly 360 canbe coupled to any portion of the bracket assembly (e.g., the firstbracket member 320), and includes the wiring 361, connector 362, andcircuitry (not shown) to electrically couple the sockets 364 (and thusthe LED light assemblies) to a power source (not shown).

The second end portion 322 includes a set of second sockets 365, eachconfigured to be coupled to and mechanically support the LED lightassembly. Similar to the arrangement described above for the bracket220, the second end portion 322 defines a series of indentations andcorresponding mounting holes. Each socket 365 is mounted within one ofthe indentations, and is retained in place by a protrusion or clip thatis locked within the mounting hole. In other embodiments, the second setof sockets 365 can be coupled to the second end portion 322 by anysuitable mechanism. The first socket 364 coupled to the first endportion 321 and the second socket 365 coupled to the second end portion322 are spaced and oriented to couple a selected LED light assemblybetween the first socket 364 coupled to the first end portion 321 andthe second socket 365 coupled to the second end portion 322. In someembodiments, the LED light assembly includes a T8 LED light tube.

As shown, the second end portion 322 does not provide an electricalconnection between a power source (not shown) and the LED lightassemblies coupled thereto and/or does not include any electroniccomponents nor other wiring of the electronics assembly 360. Thus, thesecond sockets 365 provide only mechanical support to retain the LEDlight assembly in the desired position (e.g., between the first socket364 and the second socket 365). In other embodiments, however, thesecond sockets 365 can also be electrically coupled and/or provide powerto the LED light assembly. The second sockets 365 (and any of thesockets described herein) can be suitable socket, such as a pre-wiredsocket that can hold a standard T8 LED light tube. In some embodiments,the second sockets 265 (and any of the sockets described herein) can bea BJB model 26.292 series push through lamp holder (e.g., model26.292.1111.50) or a LEVITON 13661-SWP lamp holder.

In some embodiments, the first bracket member 320 includes a first wall391, a second wall 392, and a third wall 393. The first wall 391connects the first end portion 321 to the second end portion 322. Thesecond wall 392 and the third wall 393 are each attached to the firstwall 391, with the second wall 392 being opposite the third wall 393.Collectively, the first wall 391, the second wall 392, and the thirdwall 393 define a channel 394. In some embodiments, the channel 394 canoptionally contain the electronics assembly 360. The electronicsassembly 360 can be coupled to any portion of the first bracket member320, and can include the wiring 361, connectors 362, a wiring retentionclip 366 and circuitry (not shown) to electrically couple the socket 364(and thus an LED light assembly) to a power source (not shown). In thismanner, when the bracket assembly 390 is installed, such components canbe covered and/or maintained in the enclosed channel. In someembodiments, the first bracket member 320 may also include an accesspanel 327 movably coupled about an access opening 337. The access panelcan provide access to the enclosed channel without requiring that thebracket assembly 390 be removed from the mounting structure. Forexample, in some embodiments, the electronics assembly 360 (includingthe wiring or connectors) can be accessed for service or replacementafter the bracket assembly has been installed, and without requiringremoval of a portion of the bracket assembly 390. In some embodiments,the access panel is secured by a fastener 325 as shown in FIG. 24. Someembodiments will include will include a pre-attached safety label 370affixed near the access panel 327, though the label may be placed at anydesired location along the bracket assembly 390.

The second bracket member 340 defines a longitudinal axis A₂ (see, e.g.,FIG. 27) and includes a first end portion 341 and a second end portion342. The first end portion 341 of the first bracket member 340 includesa second connector portion 351. The second connector portion 351 isconfigured to engage the first connector portion 335 to movably couplethe second bracket member 340 to the first bracket member 320 andsupport the weight of the second bracket member 340. In particular, thesecond connector portion 351 includes a series of connecting tabs 352configured to engage the first bracket member 320 when the connectingtab 352 is inserted into the slot 335 of the first bracket member 320.As shown in FIG. 34, the connecting tab 352 is coupled to the secondconnector portion by a perforated connection 354, which facilitates theengagement of the connecting tab 352 in the slot 335. In otherembodiments, however, the second connector portion 351 can be anysuitable mechanism or structure to facilitate coupling the first bracketmember 320 to the second bracket member 340. For example, in someembodiments, the second connector portion need not include perforatedtabs, but can instead include hooks, ball-and-socket connectors, or thelike.

The second end portion 342 of the second bracket member 340 includes asecond socket 364. Similar to the arrangement described above for thebracket 220, the second end portion 342 defines a series of indentationsand corresponding mounting holes. Each socket 365 is mounted within oneof the indentations, and is retained in place by a protrusion or clipthat is locked within the mounting hole. In other embodiments, the setof sockets 365 can be coupled to the second end portion 342 by anysuitable mechanism. The second sockets 365 are configured to be coupledto a LED light assembly. The second bracket member 340 does not containany of the optional electronics assembly 360. Thus, the set of sockets365 provide only mechanical support to retain the LED light assembly inthe desired position (e.g., between the first socket 364 of the firstbracket member 320 and the second socket 365 of the second bracketmember 340). In other embodiments, however, the second sockets 365 ofthe second bracket member 340 can also be electrically coupled and/orprovide power to the LED light assemblies coupled thereto.

As shown, the second bracket member 340 includes a first wall 395, asecond wall 396, and a third wall 397. The first wall 395 connects thefirst end portion 341 to the second end portion 342. The second wall 396and the third wall 397 are each attached to the first wall 395, with thesecond wall 396 being opposite the third wall 397. Collectively, thefirst wall 395, the second wall 396, and the third wall 397 define achannel 398. In some embodiments, the second bracket member 340 may alsoinclude an access panel 327 movably coupled about an access opening 337.The access panel can provide access to the enclosed channel withoutrequiring that the bracket assembly 390 be removed from the mountingsurface. For example, in some embodiments, the electronics assembly 360(including the wiring or connectors) can be accessed for service orreplacement after the bracket assembly has been installed, and withoutrequiring removal of a portion of the bracket assembly 390. In someembodiments, the access panel is secured by a fastener 325 as shown inFIG. 24.

The second bracket member 340 is configured to move relative to thefirst bracket member 320 between a first position and a second positionto facilitate installation about a strip lighting fixture. The firstlongitudinal axis A₁ of the first bracket member 320 and the secondlongitudinal axis A₂ of the second bracket member 340 define a firstbracket angle when the second bracket assembly 340 is in the firstposition, the first longitudinal axis A₁ and the second longitudinalaxis A₂ defining a second bracket angle when the second bracket assemblyis in the second position, the second bracket angle less than the firstbracket angle. Specifically, prior to installation, the bracket assembly390 can be assembled (i.e., transitioned from a first, or disassembled,configuration, to a second, or assembled, configuration) by insertingthe tabs 352 of the second bracket member 340 into the slot 335 of thefirst bracket member 320, as shown in FIGS. 29 and 30. When bracketassembly 390 is in its second configuration (i.e., the initial assembledconfiguration), the second bracket member 340 is movably coupled to thefirst bracket member 320. Moreover, when bracket assembly 390 is in itssecond configuration (i.e., the initial assembled configuration, seeFIG. 33), the first longitudinal axis A₁ of the first bracket member 320and the second longitudinal axis A₂ of the second bracket member 340 aresubstantially coaxial. For example, the bracket assembly can be placedon a floor or other support structure to maintain the bracket assemblyin the second configuration (i.e. with the second bracket member beingin a first position).

To facilitate installation, the bracket assembly 390 is transitionedfrom the second configuration to the third configuration (FIGS. 31 and32). To transition the bracket assembly 390 from the secondconfiguration to the third configuration, the second bracket member 340is rotated relative to the first bracket member 320 from a firstposition to a second position. When the second bracket member 340 is inthe second position, the second bracket angle is less than about 170degrees. More particularly, the second bracket assembly can be betweenabout 80 degrees and about 100 degrees. When the bracket assembly 390 isin the third configuration, the second end portion 322 of the firstbracket member 320 and the second end portion 342 of the second bracketmember 340 are brought closer together. This arrangement facilitateseasier handling of the bracket assembly 390 for installation.

After the bracket assembly 390 is in the third configuration, the firstbracket member 320 can be moved over a strip lighting fixture (orthrough a troffer opening) and into contact with a mounting surface. Insome embodiments, the strip fixture (not shown) can be disposed withinthe channel 394. The first bracket member 320 can be fastened to themounting surface using any suitable mechanism. For example, as shown,the bracket assembly 390 includes with a series of mounting flanges 326defining mounting holes within which a series of fasteners 333 arecaptively fastened. Thus, a user can support the first bracket member320 by applying an upward force about with a first hand, whileinstalling the captive fasteners 333 to secure the flanges 326 to themounting surface with a second hand.

After the first bracket member 320 is fastened, the second bracketmember 340 can then be rotated and/or moved relative to the firstbracket member 320 from its second position back towards its firstposition. In this manner, the bracket assembly 390 can be transitionedfrom the third configuration to a fourth configuration. The secondbracket member 340 can be moved over the strip lighting fixture (orthrough a troffer opening) and into contact with a mounting surface. Insome embodiments, the strip fixture (not shown) can be disposed withinthe channel 398. The second bracket member 340 can be fastened to themounting surface using the captive fasteners 333 as described above.

In some embodiments, the first bracket member 320 is configured so thatthe second wall 392 is spaced apart from the third wall 393 such thatthe channel 394 has a first width (see e.g., the first width L_(A) shownfor the second bracket member 340 in FIG. 37). The first width L_(A)corresponds to the fluorescent strip light being converted to an LEDlight. For example, in some embodiments, the first width can correspondto a five-inch strip width. As shown, the first bracket member 320includes a movable mounting flange 326 coupled by perforations 348 to atleast one of the first wall 391, or the second wall 392. The movablemounting flange is spaced apart from the third wall 393 by such adistance that a portion of the channel 394 can be transitioned to have asecond width L_(B) (see FIG. 37). The second width corresponds to asecond mounting structure of the fluorescent strip light being convertedand is less than the first width. For example, in some in someembodiments, the first width can correspond to a 4.25-inch strip width.Moreover, other embodiments include additional movable mounting flange326 coupled by perforations 348 to at least one of the first wall 391,or the third wall 393. In some embodiments, the movable mounting flangesare constructed with mounting holes 332 and in some embodiments, themounting holes contain captive fasteners 333. The inclusion of captivefasteners enables bracket assembly 390 to be more quickly installed.

Similarly, the second bracket member 340 is configured so that thesecond wall 396 is spaced apart from the third wall 397 such that thechannel 398 has a first width L_(A) that corresponds to the fluorescentstrip light being converted to an LED light. The second bracket member340 includes a movable mounting flange 326 coupled by perforations 348to at least one of the first wall 395, or the second wall 396. Themovable mounting flange is spaced apart from the third wall 393 by sucha distance that a portion of the channel 398 has a second width (seee.g., the second width L_(B) shown for the first bracket member 320 inFIG. 37). The second width corresponds to a second mounting structure ofthe fluorescent strip light being converted and is less than the firstwidth. In addition to the above, other embodiments include additionalmovable mounting flange 326 coupled by perforations 348 to at least oneof the first wall 395, or the third wall 397. In some embodiments, themovable mounting flanges are constructed with mounting holes 332 and insome embodiments, the mounting holes contain captive fasteners 333. Theinclusion of captive fasteners enables bracket assembly 390 to be morequickly installed.

In some embodiments, the mounting flanges 326 can include a hole throughwhich a fastener can be placed to secure the bracket assembly 390 to astrip (not shown) or other mounting structure. For example, referring toFIGS. 34 and 35, the mounting flange can include a hole 332.Additionally, the mounting flanges 326 can include a second perforation348′ along the edge where the horizontal portion of the flangeintersects the vertical portion of the flange. In this manner, when theflange 326 is deformed inward to accommodate a narrower mountingstructure, the end portion of the flange 326 can be removed via thesecond perforation 348′, as shown in FIG. 35. Moreover, although theflanges 326 are shown and described as allowing the bracket assembly 390to accommodate either a five-inch or 4.25-inch mounting structure, theflanges can be defored to any suitable position to accommodate a widthof anywhere between four inches and five inches. For example, in someembodiments, the flanges 326 can be bent along the first perforation 348by an angle of greater than ninety degrees (to accommodate a width lessthan 4.25 inches).

FIG. 38 illustrates a method 30 of installing a LED lighting fixture,according to an embodiment. Although the method 30 is described inconjunction with the bracket assembly 390 shown and described above, inother embodiments, the method 30 can be performed using any suitablebracket assembly described herein. The method includes moving a bracketassembly such that a first bracket member (e.g., the first bracketmember 320) covers a first end portion of a mounting fixture, at 32. Anend portion (e.g., the first end portion 321) of the first bracketmember includes a first socket configured to be electrically coupled toa first end portion of a LED light assembly. A second bracket member(e.g., the second bracket member 340) of the bracket assembly is movablycoupled to the first bracket member and is suspended from the firstbracket member during the moving. An end portion (e.g., the second endportion 342) of the second bracket member includes a second socketconfigured to be coupled to a second end portion of the LED lightassembly.

The first bracket member is secured to the first end portion of themounting fixture with fasteners captively coupled to the first bracketmember, at 34. Once the first bracket member is secured, the secondbracket member is rotated relative to the first bracket member until thesecond bracket member is in the desired location about a second endportion of the mounting fixture, at 36. In some embodiments, the secondbracket member can be rotated at a coupling interface between the firstbracket member and the second bracket member (e.g., the connectingportions 351 and 335, described above). In other embodiments, the secondbracket member and/or the first bracket member can be deformed tofacilitate the rotation.

The second bracket member is then secured to the second bracket memberwith fasteners captively coupled to the second bracket member, at 37. Insome embodiments, the method 30 optionally includes coupling a first endportion of the LED light assembly to the first socket (i.e., the socketon the first bracket member), at 38, and coupling a second end portionof the LED light assembly to the second socket (i.e., the socket on thesecond bracket member), at 39.

Although the bracket assembly 200 is shown and described as beingmonolithically constructed, in other embodiments, certain portions of adeformable bracket assembly can be monolithically constructed and otherportions can be separately constructed and later joined to thedeformable portions. For example, in some embodiments, the vertical (orlateral) edges 230 described above can be separately constructed membersthat are joined to the first wall 291. Such an arrangement can providemore flexibility regarding the arrangement between a central portion (orchannel) and the end portions. For example, FIGS. 39-41 a portion of abracket 520 according to an embodiment. The bracket 520 can be used withor make up a part of any of the bracket assemblies described herein,including the bracket assembly 290. The bracket 520 includes a first endportion 521, a second end portion, and a central portion 523. Thebracket assembly 590 is similar in many respects to the bracket assembly290 described above, and therefore certain aspects (e.g., sockets,wiring, etc.) are not described in detail below.

As shown in FIG. 39, the first end portion 521 (and the second endportion, not shown) each include a lateral member 530 that is separatelyconstructed from the central portion 523. The lateral member 530provides the structure to which a series of sockets (e.g., the sockets264 or 265 described above) can be mounted. More particularly, thelateral member 530 defines a series of indentations 528 within whicheach socket can be mounted. The lateral member 530 also defines a seriesof mounting holes 572 and pass-through openings 571. The mounting holes572 provide a location to which the central portion 523 can be coupled.The pass-through openings 571 provide a passageway through whichportions of an electronics assembly (e.g., the electronics assembly260), such as a wiring harness, can be disposed. By including multiplemounting locations and pass-through openings 571, the lateral member 530can facilitate mounting the central portion 523 in several differentlocations. For example, as shown in FIG. 40, in some embodiments, thecentral portion 523 can be coupled to the lateral member 530 such thatthe channel of the central portion 523 is centrally coupled (i.e., thecentral portion 523 bisects the lateral member 530). In otherembodiments, as shown in FIG. 41, the central portion 523 can be coupledto the lateral member 530 such that the channel of the central portion523 is offset. This arrangement can accommodate installation into avariety of different troffers.

The lateral member 530 includes a series of flanges 573, and the centralportion 523 includes a series of flange 526. The flanges 573 and theflanges 526 can be used to couple the bracket 520 to an inner surface ofa troffer, as described herein.

While various embodiments of the invention have been described above, itshould be understood that they have been presented by way of exampleonly, and not limitation. Where methods described above indicate certainevents occurring in certain order, the ordering of certain events may bemodified. Additionally, certain of the events may be performedconcurrently in a parallel process when possible, as well as performedsequentially as described above.

In some embodiments, the central portion of the bracket does not containnotches but rather has a telescoping design such that the bracket canslide between a first linear configuration of a length Lx and a secondlinear configuration of a length Ly, where Ly is less than Lx. In thisembodiment the user holds both ends of the central portion of thebracket and slides the bracket into a second configuration. The userthen inserts the bracket into the internal volume of the troffer of anexisting lighting fixture. Once in the internal volume of the troffer,the user can slide the bracket back into a first configuration so thatthe first end portion and the second end portion of the bracket extendto touch the ends of the troffer. In some embodiments, the telescopingdesign can be spring-loaded such that the bracket is biased in the first(or expanded) linear configuration.

The bracket 120 (and any of the brackets shown and described herein) canbe made of any suitable light-weight metal that can be bent orconfigured to be bent. In some embodiments, the bracket 120 will includea pre-attached safety label (See FIG. 9, 270).

Although various embodiments have been described as having particularfeatures and/or combinations of components, other embodiments arepossible having a combination of any features and/or components from anyof embodiments where appropriate. For example, any of the brackets shownand described herein can include any features of another bracket shownand described herein. As one example, the bracket assembly 290 caninclude the quarter-turn fastener 425 shown and described with respectto the bracket assembly 490.
